Scalpel handle sheath with blade remover
A scalpel handle sheath includes a body defining a first end and an arm adjacent the first end, the flexible arm having a first boss extending inwardly therefrom and a second boss extending outwardly from the arm. The scalpel handle sheath also includes a shield coupled with the body and slideable between a retracted position and a removal position. The shield defines an edge applying an inward force on the second boss during movement of the shield from the extended position to the removal position and a removal flange extending within the shield and passing the first end of the body during movement of the shield into the removal position.
1. A surgical device assembly, comprising:
a sheath, including:
a body defining a cavity open to a first end of the body and an arm adjacent the first end, the arm having a first boss extending inwardly therefrom; and
a shield coupled with the body and slideable between a retracted position and a removal position, the shield defining an edge applying an inward force on the second boss during movement of the shield from the extended position to the removal position and a removal flange extending within the shield and passing the first end of the body during movement of the shield into the removal position; and
a scalpel including a handle received within the cavity.
2. The surgical device assembly of claim 1 , further including a blade, wherein:
the scalpel handle defines a holder end of the handle extending beyond the first end of the body; and
the blade is retained on the holder end of the handle and is exposed when the shield is in the retracted position.
3. The surgical device assembly of claim 2 , wherein the removal flange further applies a force on the blade in a direction away from the first end of the body of the sheath during sliding into the removal position so as to decouple the blade from the holder end.
4. The surgical device assembly of claim 3 , wherein the removal flange applies pressure on the blade when decoupled to retain the blade within the shield.
5. The surgical device assembly of claim 2 , wherein the first boss is moveable by flexing of the flexible arm between a first position and a second position, the first boss being positioned away from the blade when the arm is in the first position and applying a bending moment to the blade when the arm is in the second position, the bending moment being below a removal threshold of the blade from the holder end of the handle.
6. The surgical device assembly of claim 2 , wherein:
the shield is further slideable through an extended position between the retracted position and the removal position; and
the blade is exposed when the shield is in the retracted position and concealed when the shield is in the extended position.
